KINGSTON — The city has received a $1.1 million grant for repairs on the Washington Avenue sinkhole, federal authorities announced Friday.

The U.S. Economic Development Administration grant will “restore productivity by reverting traffic flows through the city for commercial and transit vehicles back to streets designed for such purposes.”

The sinkhole shut Washington Avenue for much of 2011 and since mid-April 2012. The thoroughfare isn’t expected to reopen until late summer 2013.

Total repair cost is expected to run more than $2 million. The city has already issued bonds for nearly $1 million of work, said mayor Shayne Gallo.

But avoiding further bonding will limit the city’s long-term debt and improve its overall financial health, Gallo said.

Kingston worked with Sen. Kirsten Gillibrand’s office to apply for the grant six months ago. Gallo received the good news Friday morning.

The U.S. Department of Commerce said its money will go toward damage resulting from flooding associated with Irene. Although the initial problems predate Irene by several months, runoff from the flooding overwhelmed the city’s century-old stormwater tunnel and hastened its collapse.

Four projects nationwide received a combined $5.5 million Friday from federal grants.
